問題描述

我已閱讀 Android:將 EditText 限制為數字 和 如何在 android 的 EditText 上顯示數字鍵盤?.不幸的是，它們似乎都不符合我的需求.

I have read Android: Limiting EditText to numbers and How do I show the number keyboard on an EditText in android?. Unfortunately, none of them seems to fit my needs.

我想將我的 EditText 輸入限制為僅限數字.但是，我也希望允許有符號和/或十進制輸入.

I want to restrict my EditText input to only numbers. However, I also want to allow signed and/or decimal input.

這是我當前的代碼(我需要以編程方式執行此操作):

Here is my current code (I need to do this programmatically):

EditText edit = new EditText(this);

edit.setHorizontallyScrolling(true);
edit.setInputType(InputType.TYPE_CLASS_NUMBER);

有了這個，我的 EditText 愉快地將所有輸入限制為數字.不幸的是，它不允許任何其他內容，例如小數點.

With this, my EditText merrily restricts all input to numerical digits. Unfortunately, it doesn't allow anything else, like the decimal point.

如果我將該行更改為 edit.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL)，EditText 將接受所有輸入(這不是我想要的......).

If I change that line to edit.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL), the EditText accepts all input (which isn't what I want...).

我嘗試過組合標志(絕望地想看看它是否可行):

I've tried combining flags (in desperation to see if it would work):

edit.setInputType(InputType.TYPE_CLASS_NUMBER);
edit.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL)
edit.setInputType(InputType.TYPE_NUMBER_FLAG_SIGNED)

這也不起作用(EditText 像往常一樣接受所有輸入).

That didn't work either (the EditText accepted all input as usual).

那么，我該怎么做呢?

推薦答案

嘗試使用 TextView.setRawInputType()對應android:inputType屬性.
